- **New Features**
- Introduced a new "init" command that creates a standardized YAML
configuration file (rollkit.yaml) for simplified node setup.
- Added new logging options, including configurable log formats (plain
or JSON) and enhanced error tracing.

- **Improvements**
- Enhanced node startup and execution flows for better stability and
performance.
- Streamlined configuration management by migrating from TOML to YAML
and upgrading key dependencies.
